To all fte/tom fit may concern: y

Be it `known vthat I, PER'OY H. FINDER, a citizen ofthe United "States, residing at New York city, in the county of New York and State of New York, have invented a new and useful Improvement in Steanr Separators, of Whichthe following isy a specification.

This invention relates to a combined steam ,separator and feed water heater, and has special reference to improvements upon the apparatus shown in the patent to Roberts No. 720,740, dated Feb. 17, 1903.

The object `of the present invention is to provide a more efficient separation of the grease, oil or other mattei' suspended in eX- haust steam, and at thesame time to prevent short circuiting of the steam ,around theA The steam sometimes tends to pass over the surface of the oil drip separating baffles'.

compartment and below the separating baffles, without being cleaned. This is found to be due to the greater resistance of the steam path through the baffles, as compared with the less resistant path through the drip chamber below the baiiies. By the present invention, this difliculty is avoided, at the same time a partial purification of the steam is effected, and the drips separated, before the main purification of the steam in passing through the chain baffles.

The invention is shown in a preferred form in the accompanying drawings wherein,

Figure 1 is a longitudinal section of a separator and feed water heater embodying the invention,

Fig. 2 is a cross section.

1.1epresents the body of the separator of generally cylindrical form having the inlet 2 for exhaust steam, or steam which is to be purified, and opening into the preliminary mufling, separating, and expansion chamber 3. The heavy materials carried in the steam tend to separate from the steam as it enters chamber 3, owing to its expansion, reduction in velocity and change of direc* tion, and heavy drips are drawn off through outlet 4;. Chamber 3 is provided with a dam plate 5 and separated therefrom is a second dam plate 6 having its upper pordrip chamber 7 and the discharge chamber 8 from the feed water reservoir 18. 9 repchain baffles, and also have the function of adding additional separating surface with outcausing the total capacity to be reduced. After the steam has passed through the chain baffles into chamber 8, any further condensation runs down the inclined surface of the dam plate` 6 into the chamber' 7, and steam which passes out through outlet 15 is completely cleaned, and able to be further used in any desired manner. As herein shown the clean steam may be discharged from out let 15 into a heating system and thence into the feed Water reservoir 18 by return inlet 21, or may be discharged directly into chainber 16 and thence by pipe 17 into the feed water reservoir 18. 19 is a cold water supply tube which discharges through a water nozzle 20, and 26 is a pipe which receives the returns from inlet 21. The clean steam entering chamber 16 heats both the returns which are discharged in the form of a lateral spray from nozzle 22 carried by pipe 26, and also the cold make up water which is similarly discharged by nozzle 20 connected to tube 19 inside pipe 26, the heatedvwater flowing by gravity through pipe 17 into the feed water reservoir 18. The water in reservoir 18 can overiow after a certain level is reached, or can be controlled by a float in a well understood manner, being drawn ofi as required through pipe 23.

The heavy drips from chamber 7 can be withdrawn through plug 25 and chamber 18 may have a plug 24: for blow-off purposes.

The various accessories which may be used, such as a governor controlled feed pump, etc., are not shown herein, as devices for controlling the water level of a feed water heater of this type and for supplying and taking Water therefrom are well known and do not require further description.

What is claimed, is:

l. A steam separator comprising an expansion chamber having drip retaining means, a dam plate Vat the inner lower end thereof, a baffle chamber above and horizontally beyond said dani plate containing large surfaced `vflexible baflles, a dam plate closing said baffle chamber, a single secondary drip chamber below said baille cha`1nber and between said dam plates opening freely into said baille Chamber, and means in said secondary drip chamber obstructing the steam flow therethrough to'a greater extent than the normal floW through Said baffles.

2. A lsteam separator comprising an expansion chamber effecting an initial vseparation and having its bottom closed to retain drip, a baffle chamber containing oil separating flexible baiiies communicating With `the upper portion of said expansion chamber, a secondary drip chamber below Said baiiies, separated from said expansion chamber at the bottom by a partition and opening freelyin said baffle chamber, vertical baffles in said secondary drip VChamber for obstructing the steam flow ltherein to a greater extent than through said first mentioned baies, a plate closing both lthe first baffle chamber and the secondary drip charnpansionfchamber containing a series of flex# ble baies, and separated at the bottom from said expansion chamber by a partition, a secondary drip chamber formed 'by said partition `below' said baffle hamlber, plate bafes spaced above the bottom of ASaid secondary drip challibrbeflow said Vrst named baffles forv4 obstructing the steam flow" in,

said secondary chamber-'to agreater extent than 'through said fiexible baiiles, a SCQIld partition having its upper end inclined upwardly a-Way from said baiiies and closing both the baffle Chamber and the r,s eemfldary Idrip chamber, and a ,steam outlet from said baffle chamber above said inclined portion- In 'testimony whereof, I yhavesi,f ;ned my name to this specification, this `8th day of February 1917.
